I signed up to one com believing they would lower my bill from the previous supplier. They told me that I would be paying £14 per month. I asked multiple times if that was the total amount and if there were any hidden charges. The answer was always no. When I had signed up and got my first 2 months bills they were at full price plus vat(no mention of hidden vat charge) 3rd month I found out I'm paying £24 pounds per month as there is a hidden line rental charge as well on the mobile contract. They didn't send a breakdown or welcome email with charges etc until I complained and made a query about it all. Total misrepresentation of pricing and how it all works. Wish I'd never changed.
